SPECIFICATION forming part of Letters Patent No. 541,238, dated J une18, 1895.

Application filed March 26, 1395. Serial No, 543,197. (No model.)

To a/ZZ whom t may concern:

Be it known that I, HARLEY F. KENDALL, a citizen ot' the United Statesof America, residing at Springfield, in the county of Hampden and Stateot' Massachusetts, have invented new and useful Improvements in Pedalsfor Bicycles, ot' which the following is a speciiication.

This invention for improvements in bicycle pedals more particularlypertains to improvements in the means of connection of the pedal-shaftwith the crank, and in the means of connection ofthe foot-bearing bladesof the pedal-frame with the arms which at their extremities support theblades; and the invention consists in the constructions and combinationsof parts all substantially as will hereinafter fully appear and be setforth in the claims.

Reference is to be had to the accompanying drawings, in Which- Figure 1is a side view of the pedal and a portion of the crank to which it isattached. Fig. 2 is a plan View, the detachable rubbers and the conningdevices therefor being indicated by a dotted line. Fig. 3 is a centralhorizontal sectional view taken on line 3 3, Fig. 1, 011e of thedetachable rubbers and the confining means therefor being herepositively shown. Fig. 4 is an elevation and sectional view as taken onthe line 4 4t, Fig. 3. Fig. 5 is a perspective view showing thepedalshaft and various other parts to be hereinafter more particularlyreferred to. Fig. 6 is an illustration of the inner and outer faces ofthe end of the crank. Fig. 7 is a perspective view of the sleeve ortubular v.center ot the pedal-frame. Fig. 8 is a perspective view of oneot' the fastenings for the rubber. Figs. 9 and 10 are sections in detailtransversely through the end of the crank on the lines 9 9 and l0 10,Fig. 6.

In the drawings, A represents the pedalshaft, B represents thepedal-frame and C represents the crank. The crank has the cruciformopening, D, two of the wings, 11, 11, of which extend straight throughthe crank from face to face, while the two wings, 12, 12, which are atright angles to those, 11, 11, extend only partially through thethickness of the crank, their bases constituting solid seats, 13, 13.

These bases are preferably inwardly beveled. The pedal-shaft has its endof attachment formed with the radial lugs, ci, a., the width of whichcorresponds to that of the said severalV wings, 11, 12, of the opening,D. The pedal-shaftis, inside of its lug-provided end, screw-threaded andreceives thereon the nur, b. By screwing the said nut inwardly,sufficiently, the pedal-shaft may be slipped 6o removed from the crank(as it may be by inwardly turning the nut on the pedal-shaftsufticiently far) the nut is not detached, and there is no liability ofits becoming lost.

The pedal-frame embodies the opposite foot-bearing blades, d, d, and thetransverse arms,f,f, to the ends of which the said arms are connectedand which Vare intermediately constructed with the ball-cases as usual,and this frame also preferablycomprises the tube, g, on the reduced endsof which the parts,f, f, are closely tted. The foot-bearing blades, d,d, have the lips, h,'h,vstruck up from portions ot the blades withintheir edges, these lips standing inwardly at right angles to the lengthof the blade. The extremities ot the arms,f,f, overlap these ears andare held by the screwsnl. Bolts with nuts might be used, but the screwsas shown are deemed preferable.

In order to impart additional stiffness to the connection between theblades, d, and arms,f, the ends ot' the arms are formed with theseparatedtenons, 20, 20, (see Figs. 1 and 5,) which loosely enter themortises, 22, therefor in the blades.` The aforesaid set screws, in,constitute the entire connections tor the said parts, cl and f, thenccessityot' upsetting or riveting the endsof the tenons being obviated.Therefore, when it becomes desirable to remove a blade, in the event ofbreakage,

ICO

distortion, damage, and for the purpose of repairing `the pedal orsharpening the points, it is only necessary to remove the screws, i.

, It will be perceived from the illustrations that a combn ation pedalis provided whereby, at pleasure, the rider may have a rat-trap or arubber pedal.

The rubbers, G, consist of fiat bars having a width greater than that ofthe blades or in any event sufficient to extend beyond the edge or edgesof the blades, and the rubbers are held firmly to the blades, at theouter side thereof, by the metallic clampstrips,j. The rubbers andclamping strips are connected by means of the bolts, m, having thelateral extending lugs, m2, 'm2, one or more, the nuts, m3, and theprovision of the openings, n, through the pedal-blades which arepractically identical so far as their form is concerned withthose-hereinbefore particularly described as being provided in andthrough the attaching ends of the crank. The nuts are applied at theouter ends of the bolts. By unscrewing the nut sufticiently far,-notnecessarily removing them from the bolts,- the bolts may be pushedendwise inward so that the lugs, m2, clear the non-penetratingsocket-wings in which they had been seated, permitting the bolts to begiven a quarter turn, whereupon the bolts, rubbers, and clamping stripsmay bevall bodily removed from the pedal and without disconnection ofthe last enumerated parts.

In this pedal, I have provided at the inner bearing (as well as theouter bearing) a cone, t, which is formed separately from the pedalshaftand is adjustable longitudinally thereon by reason of itsscrew-engagement with the threaded portion, fr, at the extremity of theshaft, which is adjacent the crank. The same screw-threads may becontinued, from the place Where the nut, b, is set up, to Within thebearings. This cone has outside'ot' the ballrace the outfiying tlange,t2. The ball-raees Aare surrounded and in part constituted by, the

endwise projecting hub, u, which is brought integrally With thepedal-trame and this is externally screw-threaded and receives thedust-cap, fu, which has its outer end wall o1* head centrally andcircularly apertured to surround with closeness, and yet withoutobstructing the free rotation of the pedal, the

inner boundary of the ball-race which is of` less width than thediameter of the balls. When the pedal-frame is removed from the shaft,the balls are retained against dropping out of the race bythe washer.The washer may be removed by the use of a knife or otherwise. y

Having thus described my invention, what I claim, and desire to secureby Letters Pat:l

ent, is-

1. In a crank and pedal for bicycles, the combination with thepedal-shaft having at its end one or more laterally extending lugs andscrew-threaded within such end of the crank having the transverseopening with the penetrating and non-penetrating wings, and the nutscrewing on the shaft and against the inner face of the crank,substantially as and for the purpose set forth.

2. In a pedal, the combination with thef'oot-V bearing blades, d, eachhaving the inwardly extending ears, h, h, struck up from internalportions of the blade and also having the adjacent mortises, 22, ot' thesupporting arms,f,

f, having the tenons at their ends entering said mortises, theextremities of the'said arms overlapping said ears, and the'set-sci'ews,1', fi, confining the ears and arms, substantially as described. A
